This week on Car Talk, The Elvis Idle meets the Mechanic's Shrug, as Tom and Ray try to diagnose a Nissan's intermittent stutter. Meanwhile, strange things are happening in Waccabuc, New York, where Sally heard a loud electrical charge and saw a flash of bright light while driving under a power line. Also, Brad's got a Hydrological and Meteorological crisis, with water appearing in his Civic's spare tire well; Jack's horn went from sounding like James Early Jones to Pee Wee Herman overnight; and Melissa's decision to use her Jeep's heater as a clothes dryer may have expensive consequences. All this and lots more, this week on Car Talk.
